STOP-MOTION FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 314,153, dated March 17, 1885. Application mm May 18, was. n model.)

To aZZ whom, it may concern.-

Be it known that I, LEAVITT L. Summer, a citizen of the United States, residing at Manchester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Stop- Motions for Spinning-Frames, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is an end elevation, partly in section, of so much of a ring-spinning frame as is necessary to show my invention in connection therewith, my improved stop-motion device being represented in position previous to dofling, the ring-rail being in the upper -part of its traverse. Fig. 2 is a corresponding view showing the ring-rail near the lower part of its traverse and the stop-motion already actuated. Fig. 3 is a top view of the shipping device, showing the connectionbf the stop-motion device therewith. Fig. 4 is a partial end view and partial transverse section of a ring-spinning frame with my im- --proved stop-motion applied thereto. Fig. 5

is a side View of one end of the frame, a portion of the frame-work being removed to show the operative parts connected with the stop motion. 1

Like letters designate corresponding parts in all the figures.

My improved stop-motion is double-acting, or acting and resetting and positive, and fully accomplishes the purpose of stopping the waste of thread when doffing.

In the drawings, A represents the ring-rail of the spinning-frame; B, the bolster-rail; O, the step-rail, and D a bobbin partly filled with thread.

My stop-motion device is preferably mounted on the inside of the bolster rail B, as

- shown. It however may be applied to other parts of the spinning-frame, particularly to the lifter-rod or the lifter-rod arm. The stand E, which sustains the working parts of the stop-motion, has a clamp, a,which is secured to the bolster-rail by a screw or screws, b.

The working parts of the device are aplunger, G, playing up and down in a tubular socket, c, a latch, H, pivoted to the upper end of the plunger and arranged to be'struck by the ring-rail when the latter descends for doffing, and a lever, I, pivoted to a projecting arm, (I, of the stand and pivoted at one end to the lower end of the plunger, or connected therewith by a shackle-1ink,f. It is this 1ever I that operates the shipping device by its inner end lifting the lower end of a shippinglever, K, thereby depressingthe upper end of the lever and disengaging it from a sleeve or shoulder, g, of the shipping-rod L, the shipping spring 71, Fig. 3, thereon, thereupon moving forward and shipping the driving-belt from the driving-pulley M to the loose pulley N. The shipping device is of the ordinary construction now used on spinning-frames. The belt is shipped onto the fast pulley M by moving the shipper-rod It by the hand startinglever P, from the shaft of which an arm, Q, extends and works on a coupling-pin, Z, on

the shipperrod. An adjustable stop, an, is

attached to the shipper-rod, which strikes a forked arm, n, projecting from the shippingrodL or from its shoulder or sleeve g, the shipper-rod is moved endwise to start the machine the shipping-rod L is moved with it till the leverKdrops against the end of the shoulder or sleeve The stopping of the machine is effected by the descent of the ringrail A preparatory to doffing. The plunger G is ordinarily held in its highest position by a springsuch as a spiral spring, iinside of the socket 0, (shown in Fig. 1,) which also holds up the outer end of the lever I and its inner end down,ready to operate the shippinglever K. The latch H in this arrangement of the parts stands upright, as shown in Fig. 1, and in such aposition that when the ring-rail A is drawn down by the doffing mechanism the said rail will strike the upper extreme front of the latch, and in continuing to descend will depress thereby the plunger and cause the lever I to disengage the shippinglever K from the shipping-rod L. At the moment of completing the stopping of the spinning on the frame the parts .of the .stopping device are in the position shown in Fig. 2. Then, just as the plunger is sufficiently -depressed to stop the motion, a cam projection, K, on the outer edge of the latch H, strikes the side of the socket c, which moves the latch laterally from under the ring-rail and causes it to fall over into a horizontal posit-ion in a so when notch of the socket, as indicated by dotted lines in Fig.2, out of the way of the ring-rail in spinning. The latch is again lifted by the ascent of the ring-rail in spinning by means of a chain, 0, or its equivalent, attached at one end to the latch and at the other end to the ring-rail, substantiallyas represented. The length of the chain is such that just before the bobbin D is filled with thread the ascending rail will have drawn on the chain sufficiently to liit thelatch H into a vertical position ready for the next stopping and doffing. This stopmotion is equally applicable to filling twisting and filling spinning frames.

WVhat' I claim as my invention isor 1. The tilting latch H and belt and shipper mechanism intermediate of such latch and shipper, in combination with the ring-rail A of a spinning-frame, substantially as and for the purpose herein specified.

2. The combination, with the ring-rail A, shipping-lever K, belt-shipper, and mechanism intermediate of the shipper and said shiplever I, and intermediate plunger, G, substantially as and for 25 the purpose herein specified.

3. The resetting-chain O, in combination with the tiltinglatch H and ring-rail A, sub stantially as and for the purpose herein specified.

I11 testimony whereof I affix my signature in presence of two witnesses.
